Chaotic behavior of pulsating heat pipes [PDF]
International Journal of Heat and Mass Transfer, 2009 Chaotic behavior of closed loop pulsating heat pipes (PHPs) was studied. The PHPs were fabricated by capillary tubes with outer and inner diameters of 2.0 and 1.20 mm. FC-72 and deionized water were used as the working fluids. Experiments cover the following data ranges: number of turns of 4, 6, and 9, inclination angles from 5 degrees (near horizontal)

Operando Visualization of Cathode Water Management in Proton Exchange Membrane Water Electrolyzers Using Synchrotron X-Ray Radiography. [PDF]
Adv Sci (Weinh)The cathode of proton exchange membrane water electrolyzers remains a poorly understood region despite its importance for hydrogen purity and operational safety. Operando synchrotron X‐ray radiography directly visualizes liquid water behavior and uncovers a transition from continuous to pulsating transport, providing new insight into multiphase ...

Water pulsating heat pipe [PDF]
EPJ Web of Conferences, 2019 The new experimental setup with copper-glass pulsating heat pipe has been constructed for investigation of the heat transfer problem. Pulsations of liquid slugs inside the heat pipe has been observed. It is demonstrated that with increasing of temperature difference between evaporator and condenser heat flux which can be removed is also increases.

Modeling of pulsating heat pipes. [PDF]
, 2009 This report summarizes the results of a computer model that describes the behavior of pulsating heat pipes (PHP). The purpose of the project was to develop a highly efficient (as compared to the heat transfer capability of solid copper) thermal groundplane (TGP) using silicon carbide (SiC) as the substrate material and water as the working fluid.

Mathematical modelling and parameter optimization of pulsating heat pipes [PDF]
Journal of Computational Science, 2014 Proper heat transfer management is important to key electronic components in microelectronic applications. Pulsating heat pipes (PHP) can be an efficient solution to such heat transfer problems. However, mathematical modelling of a PHP system is still very challenging, due to the complexity and multiphysics nature of the system.
